In this column in August 1982, P. V. Skipski asked if there were any users groups forming for owners of the SuperPET. John Collins of the Technical Services Department of Commodore UK replies:

Within the I.P. Sharp Associates network's Mailbox service is a group called SPET. This is, however, mainly of interest to APL users. There is also a group called TEACH, for users of APL in education. Sharp's New York office is at Suite 210, 230 Park Avenue, NY, NY 10169. Telephone (212) 557-1200.
